Abstract (en)
A Q-switched pulsed laser resonant cavity (11) having an output coupling mirror (39) with a radially variable reflectivity function across its surface and a magnification level that combine to provide a very high discrimination against transverse modes of oscillation higher than a desired fundamental mode. This resonant cavity (11) is especially adapted for use with injection seeding to limit the longitudinal modes of oscillation to one mode. The cavity arrangement (11) develops a high powered light pulsed beam (41) at its output that also has a uniform intensity profile.
